SPECIFICATION formingpart of Letters Patent No. 238,625, dated March 8 1881.

Application filed January 10,188]. (No model.)

To all whom it may concern:

Be it known that I, JEROME WHEELOOK, of the city and county of Worcester, in the State of Massachusetts, have invented certain new and useful Improvements in Exhaust- Steam Injectors and Condensers; and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part thereof, is a clear, true, and complete description of my invention.

The prime object of my invention is to provide for a simple, inexpensive, and convenient adjustment of the area of the aperture through which the volume of feed -'water, steam, and the waters of condensation are forced.

Heretofore in complex and costly structures for the purpose indicated, a means of adjustment has been provided involving screwthreaded nozzles, actuating mechanism, 850., while in the simpler classes of apparatus no adjusting capacity has been provided for, so far as my knowledge extends.

In accordance with my invention I interpose between the condensing chamber and the pipe through which water is forced by the exhauststeam a plate containing; the ejecting-aperture, which can be readily placed in position, and displaced therefrom, without material disturbance of either the condensing-chamber or said pipe, enabling a ready substitution of one plate for another containing a larger or smaller aperture, as may be from time to time requisite under the varying conditions incident to the use of injector-condensers for exhaust-steam; and to obviate the cost of a multiplicity of such plates, in accordance with a minor feature of my invention, 1 employ but one detachable plate, in combination with a bushing readily detached or applied thereto, whereby the area of the ejecting aperture may be varied by means of bushings of various thicknesses, and hence of "ariable interior capacities.

The several features believed to be novel will, after full description, be specifically detailed in the claims of invention hereunto annexed.

Referring to the drawings, Figure 1 is a central vertical section of an injector-condenser embodying the main feature of my invention. Fig. 2 is a horizontal section through line 3 Fig. 3 is a horizontal sectional view of the detachable plate and a bushing. Fig. 4 represents, in vertical central section, a series of bushings adapted for use with the detachable plate.

The condensing-chamber A, the exhauststeam nozzle B, and annular injection wateraperture 0 are substantially as heretofore, and the said annular aperture may be adjustably controlled as heretofore.

The pipe D is the one through which the feed-water, steam, and waters of condensation are forced, the condensin g chamber and pipe D being permanently mounted in position with requisite space between their coincident flanges c and I) to snugly receive the plate E, in which is the ejection-aperture 0. The clam ping-bolts d through both flanges are preferably located outside the periphery of the plate E, and I also employ, preferably, but three or four such bolts, 80 that on the removal of one or two, and loosening the remainder, said plate can readily be moved sidewise for removal or insertion without any appreciable displacement of the pipe I) or the condensing-chamber. Even if the pipe D be not permanently set in position, but merely suspended from the condensing-chamber, it will be seen that it is of consequence, in the saving of time and labor, to be able to displace and replace the aperture-plate E without wholly disconnecting said pipe from the chamber. By having several of such plates, with apertures c of different diameters, the de sired adjustment of the latter may be readily effected. Instead, however, of having different plates, a single one only may be employed, provided its aperture be suited to receive abushing, 0, as shown in Fig. 3, which can readily be detached, and another of the series of bushings, (shown in Fig. 4,) substituted therefor. The aperture 0 in the plate E may be slightly tapered from the top downward, and the bushings be correspondingly tapered, or each bushing at "its upper end may be provided with a slight flange, overlapping the upper surface of the plate E, for preventing, in either case, their longitudinal displacement by reason of the water passing through them under pressure.

On the lower side of the plate E is an annular recess, as shown at f, surrounding the aperture 0 or the bushing, as the case may be, so that such air as may be present'in the pipe D will be carried downward by the ejected column of water without liability of rising into the condensing-chamber. The annular recess may be formed by slightly extending the plate around the aperture or bushing downward below the bearing-surface of said plate; but I prefer that it be formed as shown, so that the plate may be withdrawn and replaced with a minimum of displacement of either the pipe D or the condensing-chamber.

Having thus described myinvention, I claim as new- 1. The combination, with the condensing-
